#   azconfig option ...  -- edit Configuration file for certain configurations
#
#   This is mainly a tool for MPD development; it includes some Arizona-specific
#   values.  See the installation guide for instructions about how to edit the
#   Configuration file and Makefile to define a configuration.
#
#   options are:
#
#	links	    [default] for use from source area via symlinks in ./links
#	local	    for /usr/local/bin
#	optlocal    for /opt/local/bin
#	mpdbin	    for /usr/mpd/bin
#	/path	    to put all installed files in the given path
#	dist	    for making a formal distribution (uses /usr/local/bin etc.)
#
#	multi	    build MultiMPD when possible
#	uni	    force UniMPD even if MultiMPD available
#
#	fast	    build with -O and disable debugging
#
#	gcc         use gcc (Gnu C compiler)
#	gcc2	    use gcc from "gcc2" path
#	clcc	    use clcc (CenterLine C)
#	acc	    use acc (Sun ANSIish C compiler)
#	c89	    use acc (Dec ANSI C compiler)
#
#   Unspecified options are reset to defaults, NOT left unchanged.
#
#   WARNING -- this script overwrites the mpdmap file


# look around the system and create a set of default values
